The objective of the present study was to estimate micronutrient intakes and the contribution of different food groups to micronutrient intakes in Irish teenagers. The prevalence of inadequacy of micronutrients was also assessed. Analysis was based on The National Teens Food Survey, which was carried out between September 2005 and September 2006 to establish a database of habitual food and drink consumption in a representative sample of Irish teenagers aged 13–17 years. A 7 d semi-weighed food record was used to collect food intake data from 441 teenagers (224 males, 217 females). Analysis of dietary intake data was carried out using WISP© (Tinuviel Software, Llanfechell, Anglesey, UK), which is based on McCance and Widdowson's The Composition of Foods, Sixth Edition ⁽¹⁾.

The mean intakes and the percentage with inadequate intakes of selected micronutrients are shown in Table 1 and the main food groups contributing to these intakes are shown in Table 2. The percentage with mean daily intakes below the estimated average requirement⁽²⁾ for selected micronutrients is reported as an estimate of the prevalence of inadequate intakes⁽Reference Carriquiry³⁾.

When under-reporters were excluded (males: 63%; females: 64%), the % ⩽EAR decreased (males: 6, 2, 16 for calcium, iron, vitamin A; females: 15, 60, 10, 3, 9 for calcium, iron, vitamin A, riboflavin and folate).

A significant prevalence of inadequate intakes was observed for Ca, Fe, vitamin A and folate, particularly in females.
